ELECTRICAL SIGNALIN G DEVICE.

Specication of Letters Patent.

Patented June 5, 1917.

Application tiled October 19, 1915. Serial-No. 56,720.

To all whom 'it may concern:

Be it known that I, GUY W. COMER, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois,'have'invented certain new ,and useful Improvements in Electrical Signaling Devices, of which the following is a specification.

My invention relates to improvements in electrical signaling devices for vehicles, and has for its object, the production of a device of this character which will be of simple construction and efficient inV use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompan in drawing forming a part of this speci cation, and in which,

Figure 1 is a central longitudinal section through a signaling device embodying the invention,

Fig. 2 is a rear elevation .thereof 'shown partly in section, and

Fig. 3 is a section taken on line -m of Fig. 1.

he preferred form of constructiom as illustrated in the drawing, comprises a bracket or supporting arm 1 adapted, when the device is in use, for mounting upon the vehicle in connection with which the device is employed. Fastened in the outer end of bracket l is a laterally projecting tube 2 upon which is rotatably mounted a sleeve Fixed to the sleeve 3 is a. signaling-arm 4 consisting of a front plate 4 and a rear plate 4", said arm being fastened to an an-y nular outwardly projecting 'lange' formed upon the sleeve 3 by means of bolts 6 and coperating nuts 7. The arrangement is such, as will be seen, that free oscillation. of the signaling arm is permitted upon the tube 2. No means for eli'ecting such'oscillaton is disclosed in this case, such construction being embodied in'another pending application. A

The parts 4 and ttr. of the arm 4 are connected together by nanges 8 formed at the longitudinal edges of the part 4" which embrace the corresponding edges of the part It. /The parts 4 and 4 are of tapered formation so that, upon rearward sliding of the part et, the flanges 8 will disengage from the corresponding edges of part 4 and thus permit of removal of the part 4 so as to allow access being gained to the interior of the arm. The part 4 is provided at its rearward end with a flange 9 and the part 4 is provided at its outer edge with a -lalnge position upon the part 4.

l The part 4 adjacent the outer end thereof is formed with au opening over which is arranged a lens 11 held in position4 by an annular holder 12. Arranged within the arm behind the lens 11 is an electric lamp 13 mounted in a' socket 14 fastened to the rearward side of arm member 4.

Fixed to the end of tube 2 within the signaling arm is a disk 15 of insulating material, said disk being secured to said tube by diametric pins, as Shown, and also by a nut 16 threaded upon said tube. Mounted upon the periphery of the member 15 are diametric contact plates 17 havin inwardly projecting. ears, as shown, secure to the side of member 15 by means of screws 18. The screws 18 Serve also as binding posts for connecting the contact members 1 7 with the feed wires v19 which extend through the opening through tube 2.

Copera-ting with the contacts 17 are elonment of the part 4 in sliding the same to gated` movable contacts 20, corresponding ends of which are secured by screws 21 to a block 22 of insulating material mou'nted upon the rearward vside of arm member 4. The screws 21 serve also as binding posts for connection with the conductor wires 23 leading tothe lamp socket 14. The contact members 20 are so positioned that the freeends thereof are adapted for engagement against ,the periphery of the holder member 15, a helical tension spring 24 cooperating with the contact members 20 for `normally pressing the same intoen age- 10 which serve as stops to limit the movenaling arm is in horizontal or signaling position. This being so, it will be seen that `when the arm is in lowered or non-signaling nomic-al and advantageous arrangement iiiasmuch as itpermits of passage of the feed wires to the interior of the signaling arm.

While I have illustra-ted and described the'preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modlicationsas come within the scope of the appended claims.

Having described my invention what I 5 claim as new and desire to secure by Letters Patent iS:

1. A device of the class described comprising a bracket; a signaling member rockingly supported by said bracket; an electric lamp carried by said signaling member; a make-and-break device for controlling the lamp circuit whereby the lamp circuit will be broken except when the signaling member is in signaling position, said device comprising a circular holder of insulating material fixed to said bracket; a pair of, stationary contacts mounted on the periphery of said holder at opposite sides thereof; and a pair of elongated movable contacts fixed at correspending ends to said signaling member, the opposite ends of said last mentioned contacts being adapted for engagement with theY periphery of said holder, for contact with said stationary contacts when said signaling member is in signaling position, substan-4 tially :is described.

2. A device of the class described comprising a. bracket; a signaling member roel?, ingly supported by said bracket; an electric be broken except when the signaling member,

is in signaling position, said device comprising a circular holder of insulating material lixed to said bracket; a pair of stationary contacts mounted on the periphery of said holder at opposite sides thereof; a pair of elongated movable contacts fixed at corresponding ends to said signaling member, the opposite ends of said last mentioned'contacts being adapted for engagement with the periphery of said holder for contact with said stationary contacts when said signaling member is iii signaling position; and resilient means engaging with said movable contacts for pressing the same into engagement with Said holder periphery, substantially as described.4

3. A device of the cla described comprising a bracket; a laterally projecting tube mounted in said bracket; a signalin arm rockingly mounted on said tube; an e ectric' lamp carried by said signaling arm; amakeund-break device for controlling the lamp circuit whereby the lam circuit will be broken except when said signaling ari-n is in signalinglposition, said device comprising a circular older of insulating material fixed to said tube; stationary contacts on the periphery of said holder upon opposite sides thereof; and movable contacts carried by said arm engaging against the periphery of said holder and'v adapted for engagement with said stationary contacts when said arm is in signaling position, substantially as described. y

4. A device of the class described comprising a bracket; a. laterally projectin tube mounted in said bracket through whic electrical feed wires are adapted to pass; a signaling arm rockingly mounted on said tube and inclosing the outer end thereof; an electric lamp carried by said signalin arm; a make-and-break device for contro ling the lamp circuit whereby the lamp circuit will be broken exceptV when the' signaling arm 1s in signaling position, said device .comprisingr a circular holder of insulating material lixed to said tube; stationary contacts angularly disposed with relation tov eachother on the periphery of said holder with which said feed wires are connected;.and movable contacts carried by said arm with which the lamp conductor wires engage, said movable contacts engaging against the periphery of said holder for contact with said stationary contacts when said signaling arm is' in signaling position, substantially 'as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
